Login.jsp isn't updating

I downloaded login.jsp and updated with new code. However, the login page isn't showing the same thing as the preview. How do I update the login page with the new login.jsp, I've waited two days and cleaned caches. Do I have to open blackboard ticket for this?

You shouldn't have to open a ticket, especially if you are self-hosted. I've always just uploaded the new file and refreshed the login page in my browser. Now sometimes I've had to restart the browser or open it in a new browser, but its never taken days to view. Managed Hosted may be different....IDK. You can always go ahead and open one to see what they say. Also, have you perused the list-servs? A lot of time the archives there have great information that isn't here.
